Did the aftercoolers on my Cummin's 6CTA's (8.3 450hp) several years ago and was no big deal. Not sure which Cummin's you have but it should be similar. Needed 4 new O rings and special grease used during reassembly. Purchased the O Rings from a local Cummin's dealer and the grease from the auto parts store. Removal and disassembly was relatively easy. Reassembly and install was easy as well... Had the internals of the aftercooler cleaned by a radiator shop,  I've attached a  web site that discusses how to do the job w/pictures. Should be relatively easy to do. M2C
